STENCIL-CABD-FEEDING ATTACHMENT TYPE-WRITERS.

T aZZ whom it may 00mm;

Be it known that we, ALFRED L. McCAW-,

be simple and reliahle in operation and which may be readily attached toa typewriter to permit of'thc use ofthe latter for the purposeindicated. The preferred. embodiment of the. invention shown. in thedrawings is intended for application to the Well-known Underwoodtypewriting inachinc, and is illustrated in the drawings as so applied.

It should he explained that tho stencils referred to are usually aboutfour and (mo half inches long by two inches wide; 'lhey comprise acentral rectangular field of thin paper or similar material which isinelosed around its edge-portion hy two thicknesses of paper, and thesein turn are inelosed at their edge-portion by two paste hoard.constituting a frame. The cenis adaptcd to he -noistened and whenWritten upon by a suitable machine the type punc' tures the paper or soreduces its thickness at the points of'impa'ct that it is renderedcapahle of use in the. mannerof a stencil. That is to say. bypassing anink roller over this thin field the ink will penetrate through theportions weakened or punctured by tho type and make an imprinton-quienvelop, card, or the like. placed beneath the stencil.

f'ihesc stencils are employed for addressing purposes. and are used bypublishers, advertising agencies. large commercial houses. and the like,where thousands of pieces or addrcssedmail matter are sent out atccrtain intervals. Hcretofore it has been customary.

to employ special machines for preparingthese stencils. the ordinarytypcwritmg machine not being: adapted for this purpose/ That istosay.the platen of the typewriter being round the stencil is heat or curvedtransvcrscly-upon hcing written upon; and thiivcry often renders the,stencil incapable Specification of LettcrsiPatent.

of use in the automatic machines in which they are placed for thesubsequent addressing operation.

According: to'onr invention the stencil may he readily inserted in anupright posi tion in the machine, and may be written upon and elevatedfor each new line hy turn i ing; the platen roll. in the ordinarymanner, i

the stencil as a. whole being maintained throughout in an uprightposition and pre rented from being bent or curved in'cither direction. I

means of turning; the m lled heads 8 mounts 'f ed on the. ends of theplaten shaft. Ve will here state that all of the parts of the typewriter shown are of the ordinary construction and only those parts willhe referrcd tio in this description which are necessary to; make the applieation of our invention clear. 1

Fi e will further state that before using 3 onr'inrention in addressingstencils it is necessary to reniave the ribbon and ribbon guide. This ismsrely'hy reason of the pan ticalar' construction of the machine underconsideration. as the location of the ribbon guide in the commercialUnderwood ma chine prevents the insertion of a stencil to the. requisitedistance in a straight line.

The preferred form of our attaclnnent, as ilhistrated in Figs. 1.9. 2,and 3. will now' he described.

' per edge portion of the stencil to maintain.

The numeral 9 indicates a plate which is of the length of the carriageofthe typewriter and is provided at its ends with slots 10 through whichheaded screws 11 are adapted to be inserted and screwed into aperturesin the frame members 6 at opposite ends of the carriage. At the front ofthe plate 9 there is a depending flange portion 12 which isvertically-disposed with its lowr edge located in close proximity to thesurface of the platen roll 7. This flange 12 acts as aguide, and as asupport for the upit in a vertical position at all times while it is inthe machine. Mounted on the plate 9 are two similar guide plates 13,each of which has at the front vertically-disposed flange portions 14which extend downward parallel to the flange portion 12 and serve asguides for the ends of the stencil. Each of the plates 13 is providedwith a longitudinal sl 15 through which passes a set screw 16 whichenters a screw-threaded aperture in the plate 9. The plates 13 arepreferably I applied thereto an adjusting nut 26.

bent at a right angle at their rear edge to form a flange 13 which abutsagainst the rear edge of the plate 9 and thereby assists inmaintaining'the plates and guides in correct position. By loosening theset screws 1.6 and adjusting the plates .13 toward or from each otherthe space between the guides 14 may-be lengthened or shortened to accommodate various sizes of stencils or cards. The numerals 17 indicatetwo similar spring arms which are secured to the rear edge of the plates13, as indicated at 18, and each of which is bent twice upon itself atsubstantially right angles to form a depending arm 19in the bottom orfree end of which is journaled a feed roller 20 of rubber or likematerial. The rollers 20 are positioned directly opposite the platenroller 7, and in the horizontal plane of the axis thereof, and normallythe spring arms 19 force these rollers into contact with the platen.Slidably mounted in sleeve bearings 21 near the outer ends of the plate9 are two posts 22 each of which is normally pressed downward by a coilspring 23 interposed between a collar 2t thereon and the lower sleevebowing 21. The upper end of each of these posts is screw-threaded, asindicated at 25. and plas 9 upper portion of the edge of the posts 22 isflattened at one side as indicated'at 27, and graduation marks 28 areprovided on this flat side. The posts 22 are connected at their lowerends to opposite ends of av bar 29 which L-shapcd in cross section. thefoot 30 thereof serving as a support for the stencil. VVhatsve havetermed herein as the segmentbrace is shown in Fig. l, and indicated bythe. numeral 31. In order to permit the sten- \CllS when inserted in theattachment to drop low enough to pcru t the maximum number of lines tobe Written on the stencil field, we may! provide the segment-brace 31with a longitudinal groove 32, which, in practice, extends a shortdistance beyond each side of the sector 4. This groove 32 is wide enou hto accommodate the bar 29 which norma y rests on the bottom of thegroove. groove,,however, may be dispensed with, especially when thelater model. of stencilcardis used, as with this type of card it isunnecessary to provide for the drop of the stencil-cards lower than thetop of the seg ment brace. In order to move the feed rol l-. ers 20 ashort distance away from the platen 7 to permit the insertion of astencil we provide a flat bar 33 having cylindrical ends mounted inbearings 34 on the plate 9 and provided at one end with a push-lever 35.

The bar 33 extends under and in contactwith the horizontal portion ofthe 5 ring arms 17 and by pressing the lever 35 ackward the arms 19 arethereby thrown slightly outward permitting the ready insertion of thestencil between the guides 14, and between the rollers 20 and the platen7, the stencil falling into the groove 32 and resting upon the foot 30of the bar 29. lVhen the lever 35 is-released, the sprin of the arm 17turns the bar 33 to norma In this position the field 38 of the Thiscenters of the rollers 20. By manipulating the platen in the usual way,or by turning it by means of the milled heads 8, the stencil will beraised by frictional contact with the platen caused by the pressure ofthe feed rollers 29 on the stencil which pressure is in turn caused bythe spring action of the arms 19. As each line is written the stencil ismoved up the required space for a new line, and this continues until theentire number of lines, three. or four, have been written, when thestencil is removed and a new one inserted. If only three lines are to bewritten on the stencils the adjusting nuts 26 are turned to bring the 11per graduations 28 in line with the top 0 the nut, which action raisesthe bar 29 agiven distance: and if only two lines are .to be written theadjusting nuts 26 are turned to which action r'uiscs iho bar 29 a stillfarther distance. but not somuch as to withdraw it from the groove 32 ifthe latter be employed, which then not only provides means for usbringthe lower graduation mark to position,

weenie accommodating the stencil in the machine, but also acts tomaintain the proper aimemerit of the bar 29 with the guides i The plate9 is recessed on its front side to form near its encls shoulders 39which limit the distance to which the guide plates it may be separated.The springs 23 not only serve to maintain the bar 29 in a horizontaloosi tion, but they also permit the saicl liar or scribed, or to the use0 our invention with an Underwood typewriter only except Where We haveso indicated. in the claims.
